Seat Belt Height Adjuster: Description and Operation

The current is always applied to TERMINAL ECUB of tilt and power telescopic ECU through the dome fuse. At the same time, the current also flows from power CB to TERMINAL +B of tilt and power telescopic ECU and TERMINAL 7 of power shoulder anchorage relay.

When the Ignition SW turned ON, the current flows to TERMINAL IG of tilt and power telescopic ECU through the ECU-IG fuse.

POWER SHOULDER BELT ANCHOR OPERATION (FOR DRIVER'S SIDE)
When the shoulder belt anchorage adjusting SW of the driving position memory and return SW is pushed to the down side the tilt and power telescopic ECU operates and the current to TERMINAL +B of ECU flows from TERMINAL BEM- of ECU TERMINAL 1 of shoulder belt anchor Motor --> Motor --> TERMINAL 2 --> TERMINAL BEM+ of tilt and power telescopic ECU TERMINAL GND GROUND, rotating the shoulder belt anchor Motor so that the shoulder belt anchorage moves downward while the shoulder belt anchorage adjusting SW is pushed to the down side.

For up operation, pushing the shoulder belt anchorage adjustment SW to the up side causes the, tilt and power telescopic ECU operate and the current to TERMINAL +B of ECU flows from TERMINAL BEM+ of ECU --> TERMINAL 2 of shoulder belt anchor Motor --> Motor --> TERMINAL 1 of shoulder belt anchor Motor --> TERMINAL BEM- of ECU --> TERMINAL GND --> GROUND, rotating the shoulder belt anchor Motor so that the shoulder belt anchorage moves upward while the shoulder belt anchorage adjusting SW is pushed to the up side.

The amount of movement of the power shoulder belt anchorage, which is driven by the Motor, is detected by the position sensor and the signal is input to the ECU, making it possible to perform memory and return functions for the shoulder belt anchorage position using the driving position memory and return SW.
